Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

I wrote this when I could not find Arduino code online that could accurately and reliably read 25kHz pwm signals. For reliable PWM you must handle the following edge cases: 100% or 0% PWM signal with ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

This repository contains an Arduino-based 8-channel PWM receiver code using the nRF24L01 transceiver. The receiver maps wireless signals from a transmitter to PWM signals for controlling up to 8 ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

The good thing about computers is they do your work for you, right? If you are a programmer, that doesn’t always seem to be a true statement. [Runtimemicro] has the answer, at least if you are writing ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...
